IMPRovEn lvIAI. FQRFILTERING- coLLoDIoN.

i The Schedulrfen'ed to in these Letters Patent and making part o! the-sama Be 'itifknown that I, DANIELL H Cnoss, of Bennington, in the county of Bennington and State of k1, Vermont, have invented an Improved Filtering `Collodion-Vial; and the followhjgr isrdeelaredto'be a correct description thereof. p

1 Vinlshave been made in which aglass sponthas` been fitted beneath a removable cover or cap, and provision has been made `for allowing `any collodion that x `may drip from said spout to return into the vial. It his, however, usualto allow the surplusv collodionto n drain off the glass plate into aseparate vial, so as to filter the same before it is used. l

l My invention relates to a filtering-'vial in which the filtered collodiou is made use of and the surplus collodion returned into the `main vessel to be reltered bet fore being again used upon a plut-e of glass or other` f materialfin photography. i ,i i My `invention consists in a vial or vessel containing lfcollodion, in which is a ponring-tub`e, secured at the l. upperend to a pelthrated stopper, which stopper also forms a draining funnel, `and .thebottoni of said peut, ing-tube isprovided with a. `strainer or filter, so that :fthe collodioupercolates through 'the filter into the pouring-tube, and is flowed from that over the plate,-

and the surplus is drained into the'vial through the is employed to cover the vial to prevent evaporation.

In the drawing- Y Figure 1 is a'vertical section of `the said vial, co1nx plete, and y Figure 2 is a plan, with the cap removed.

i The ,vial a is of a convenient size and-shape. The Y *stopper i) tits the upper partthereof, and has two openings, one a-fnnnel-shapgd hole, c,t`he other an `opening for the neck of the pouringtubed to pass may be necessaryto form the stopper n two parts,

he1d` together hy a winding of wire or string at' 2.'

An elastic ring, 3, maybe employed to form a tight joint between the, stopper b and vial a.

At the lower end of the pouring-tube l a filter or strainer -is attsched,lnt t. The same may be a piece of m'nslin or annel, and this prevents the passage into the tube d of any foreign substance there may he in the collodion, or which may run in with the same when surplus collodion is drained off the plate into the via'l a through the funnel c. Y

The cap lor cover .e is made `to set over the vial and around the stopper, to prevent evaporation and exclude dust. This cap covers the two openings, and is much more convenient than separate Stoppers heretofore Y used.

vial a is inclined, before the collodion ureaches the hole c; hence nothing will be spilled.

This vial is adapted to varnish, albumen, and other solutions used in photography. '-1

I claim as my inventiony y The stopper b, having a funuelshaped opening, c, for collodion to be drained off the plate into the vial lct, in combination with the filtering andpouring-tube d and cap e, substantially ras and for the purposes set forth.
